Sony was praised as being the best Android smartphone company in terms of open sourcing its firmware to the deepest level, once again Sony never fails to impress. We’ll soon be seeing the Xperia Z running Kernel 3.6!

Sony is doing a remarkable job, a while back it even open sourced it’s Alpha firmware and had previously contributed to AOSP while the Xperia S enjoyed a ‘stock-like’ experience. It will once again prove it’s engineering prowess by being the first to provide an Android 4.2.2 upgrade with a brand new Kernel 3.6.

Well to the end user it wouldn’t make a damn difference to the end user but it all comes down to the internal management of your device, the newer the kernel the better are the features, the more secure it is and the more efficiently it works. A clear example can be seen while comparing Kernel 2.6 (used in Gingerbread) and Kernel 3.x (used in
